Researchers evaluated the anti-acetylcholinesterase (AChE) and antioxidant activities of extracts and essential oils from Cyclotrichium niveum, Thymus praecox subsp. caucasicus var. caucasicus, Echinacea purpurea, and E. pallida. They found that ethyl acetate and dichloromethane extracts of CN had the highest AChE inhibition while ethyl acetate and ethanol extracts of TP showed significant antioxidant activity. Water extracts of CN and TP and the chloroform extract of EPU displayed the highest ferrous ion-chelating effect. TP's leaf and flower essential oils had the best antioxidant power. These findings suggest that these plant extracts and oils may have potential therapeutic applications.
